Clinker from Nam Viet Maritime Joint Stock Company is a Portland cement intermediate product composed primarily of tricalcium silicate (C3S) and dicalcium silicate (C2S), formed by sintering limestone and clay at 1450°C. The material has a bulk density of approximately 1.4 to 1.6 tonnes per cubic meter and is shipped in bulk or jumbo bags. Chemical analysis shows typical CaO content between 63% and 67%, SiO2 between 20% and 24%, and Al2O3 between 4% and 6%, aligning with standard Portland clinker ranges.
The clinker exhibits a standard nodular form with particle sizes averaging 3 to 25 mm, suitable for direct feeding into cement mills. It contains less than 1.5% free lime, indicating proper calcination, and moisture content is maintained below 0.5% to prevent premature hydration. The material meets typical international specifications for clinker used in Ordinary Portland Cement production, though no third-party certification is confirmed by the supplier. Variants are not specified, suggesting a standard grade suitable for general-purpose cement manufacturing.
This clinker is sourced by cement manufacturers in Southeast Asia, South Asia, and the Pacific region for use in grinding plants producing OPC and blended cements. Buyers typically require consistent chemical composition and low alkali content to avoid efflorescence in final products. Trade terms are not listed; buyers must confirm incoterms, packaging options, and minimum order volumes directly. Shipping is handled from Hai Phong Port, with bulk carriers or containerized jumbo bags common for export.

Before ordering clinker from Nam Viet Maritime Joint Stock Company, verify the chemical composition via a recent lab report showing CaO, SiO2, Al2O3, Fe2O3, free lime, and alkali content. Confirm the particle size distribution and moisture level with sieve and LOI tests. Do not rely on marketing claims; request documented test results matching ASTM or ISO standards. Ensure the material matches your cement plant’s feed requirements to avoid kiln operational issues or product failure.
Confirm the incoterms (FOB Hai Phong or CIF destination), lead time for vessel scheduling, and minimum order quantity directly with the supplier. Bulk shipments require port access and silo capacity; jumbo bags need forklift handling. Payment terms are not listed - common options include LC at sight or advance TT. Lead time may range from 10 to 25 days depending on vessel availability. Always request a bill of lading and packing list before shipment.
Conduct a third-party inspection at the loading port for quantity, packaging integrity, and visual quality. Sample clinker for laboratory testing of chemical composition and free lime. Request a certificate of analysis with batch number and test dates. Ensure documentation includes phytosanitary clearance if required by destination country. Retain samples from each shipment for quality traceability in case of disputes or performance issues.
